Prow jobs for publishing centos9 multi arch image

[chandramerla]

What this PR does / why we need it:
This PR adds multi-arch publish jobs for centos9 images.
As we've added s390x support in k8s provider (started with 1.30 slim), centos9 and gocli images as part of kubevirt/kubevirtci#1252, this PR does changes required in project-infra repo to enable the prow jobs for publishing centos9 multi-arch image.

There is another PR where publishing of multi-arch images of k8s provider is handled: #3566
